There is provided a composition comprising an oil medium, wherein particles are suspended in said oil medium, wherein said particles comprise cyclopropene and molecular encapsulating agent, and wherein said particles have median size, as measured by the largest dimension, of 50 micrometer or less. Also provided are a method of making such a composition and a method of treating plants by contact with such a composition.

The present invention relates to compositions, methods and materials for delivering a cyclopropene or other active ingredient to a plant. Provided are compositions comprising double encapsulated particles having a waxy coating and being imbedded in a resin matrix. Such double encapsulated particles are further coated with Pickering particles and suspended in an oil. The double encapsulated particles comprise a volatile compound (for example, 1-MCP complex powder) as an active ingredient. Also provided are methods for preparing such compositions and methods for using such compositions.

A stable inclusion compound for the antistaling purpose of fruit, vegetable, flower, plant, etc. is prepared from 1-methyl cyclopropene, starch and alpha-cyclodextrin or its derivative by using of a reaction system, which is composed of 1-methyl cyclopropene generator, three-pass gas washing unit, inclusion reactor and tail gas absorbing unit.

The present invention relates to new delivery systems for cyclopropenes in which compositions comprising the cyclopropene and a molecular encapsulation agent complex further comprise additional components which provide slow release of the cyclopropene from the molecular encapsulating agent with water, or release of the cyclopropene from the molecular encapsulating agent with only small amounts of water, or both. The present invention also provides methods to release a cyclopropene from such compositions as well as methods to deliver a cyclopropene compound to a plant to inhibit an ethylene response in the plant.

The invention provides a fruit and vegetable freshness retaining packaging material capable of releasing 1-methyl cyclopropene and a preparation method thereof, belonging to the technical field of a packaging material. The 1-methyl cyclopropene (1-MCP) is used as an active component and is added into a binding agent used by a dry method composite technique, so as to prepare a composite thin film using EVA / LDPE (Ethylene-Vinyl Acetate copolymer / Low-Density Polyethylene) / rubber modified film as an inner layer and using normally used polyethylene and polyethylene and or modified thin film thereof as an outer layer. When fruits or vegetables are filled into a freshness retaining bag prepared by the composite film, water gas generated by breath of the fruits or the vegetables induces the thin film to slowly release the 1-MCP in the bag; the 1-MCP is an ethylene stopping agent, and the fruits and the vegetables can be prevented from generating ethylene; the maturity of the fruits or the vegetables can be slowed, so that the goods self period and the storage period of the packaged fruits or vegetables can be prolonged; and before the fruits or vegetables are filled, water in air is not enough to release the 1-MCP. The freshness retaining function of the freshness retaining bag is not opened.

Methods of applying cyclopropene amine derivatives and compositions thereof to inhibit ethylene receptors in plants and plant material are disclosed. Methods include applying to the plant an effective ethylene response-inhibiting amount of at least one cyclopropene amine compound or composition thereof. Cyclopropene amine compounds, enantiomers, stereoisomers or salts thereof are also provided.

The present invention is directed to novel methods of increasing the abiotic environmental stress tolerance of a plant, to methods of improving the quality and / or yield of a plant crop, to methods of application of a cyclopropene such as 1-MCP to a plant, and to crops produced using said methods.

The invention disclose a aerosol preservative, the ingredients of the preservative include methyl cyclopropene, solvents, Preservative components also include stabilizing agent, solvent-like alkanes organic solvents, spirits organic solvents, or mixture of alkanes organic solvents and spirits organic solvents, stabilizers are high efficient oxidation inhibitor, or polyvinyl alcohol, or the mixture of high efficient oxidation inhibitor and polyvinyl alcohol, methyl cyclopropene can be fully uniformly mixed with each solvent, after Quantitative Filled, control jetting quantity through jetting time, 1 - MCP releases quickly after spraying.

There is provided a composition comprising an oil medium, wherein particles are suspended in said oil medium, wherein said particles comprise cyclopropene and molecular encapsulating agent, and wherein said particles have median size, as measured by the largest dimension, of 50 micrometer or less. Also provided are a method of making such a composition and a method of treating plants by contact with such a composition.

The invention discloses a 1-methyl cyclopropene slow release formulation and a preparation method thereof. The slow release formulation consists of 1-methyl cyclopropene as a core material and a covering film wrapping outside the core material, and the selected covering film is gelatin. The preparation method of the 1-methyl cyclopropene slow release formulation sequentially includes the following steps: dissolving the gelatin in water to formulate solution with the weight percentage of 2-10% and controlling the temperature of the solution between 1-4 DEG C; adding 1-methyl cyclopropene and stirring to form a gelatin-coated 1-methyl cyclopropene microemulsion; adding precipitating agent so that the microemulsion precipitates in the system and continuing to stir for 20-30min; adding a film-solidifying agent to solidify the covering film; fitering and then washing the solidified product to obtain a slurry 1-methyl cyclopropene microcapsule; and adding a separating agent in the slurry 1-methyl cyclopropene microcapsule so that the microcapsule disperses. The product is high in content of effective substances and long in slow release time. The preparation method is simple in technology and convenient in operation.

A method of treating dicot seedlings comprises contacting dicot seedlings with a composition comprising at least one cyclopropene one or more times prior to transplanting the dicot seedlings. A method of treating crop plants comprises contacting crop plants one or more times with a composition comprising at least one cyclopropene while the crop plants are at a specific development stage, such as reproductive stage.
